Kunyomi

たつ

In theory, the kunyomi of dragon is TATSU - but oddly it's never used ABOUT DRAGONS THEMSELVES. For example, if you see a dragon, you have to use the ON yomi - 'Hey! It's a ryuu!' However - CONFUSINGLY - some jukugo - such as 'seahorse' and 'tornado' use this kunyomi (TATSU). . . .It's basically the reverse of how kun and on are usually used.
